If any aikido style today had the "real goods" or was operating at a level closer to the Founder, people would be flocking to it, just like people flocked to Takeda and Ueshiba looking for something especial. Such skills would be evident in the students of this style and people would want it. The fact that there's no mass migration to any particular aikido style, and so many styles and organizations survive in parallel and none can claim superiority based on skill, tells you that everybody is pretty much on the same relative level compared to the aikido propounded by the Founder, regardless of whether your lineage is pre-War or post-War, or comes from Shingu, Iwama, Tokyo, etc. As Marc Abrams suggested, it's less imperative to discuss lineages thatn it is to concentrate on what the Founder was really doing and work to replicate it.
